Is it really a worry though, what are his options
a) asset strip - ground? training ground is outside the residential planning envelope and I believe the land belongs to Aston University anyway.
b) Sell, not a chance of re-couping his outlay and in the current economy there will be next to no potential suitors (Standaman has written some excellent pieces on this in the past)
c) Leave us to wither and die, hardly good business sense.
d) maintain what he has in the hope that Slav (or a successor) is Corberan and turns the club into a desirable asset
That's the point, none of the options are good, & even if we are promoted & establish ourselves as a Premier League club, it's unlikely that our valuation will get to anything like the alleged £200 million that Lai paid for us.
Additionally, if reports from China are correct, he wouldn't be allowed to write down the loss as that would mean cash leaving China. Not allowed under the present regime.
Also, by far the largest asset value in a football club are player contracts. If, as is now likely, player contracts are to be negotiated downwards then the sell-on value of the player would also decrease.
As commentators have said, the financial landscape will change dramatically once the coronavirus crisis is over, & from an operational level, we're probably better positioned than most, but I'm not sure how long we're going to be able to operate without a cash injection & clearly that's not going to come from our present owner.
